The invisible world beneath your feet, and why it determines everything that grows above it.
Long before the first plant, microbes were already turning rock into soil.
For most of agricultural history the farmer's eye was drawn upward, to the crop, the canopy, the sky. What happened below the surface was judged only by its results above it. If the plant grew well the soil was good. If it struggled, the answer was another bag of fertiliser.
What was almost entirely invisible was the community of living organisms making that growth possible in the first place. Hundreds of millions of them in a single teaspoon of healthy soil, so diverse and so tightly interwoven with plant life that without them agriculture as we know it could not exist.
Understanding what microbes are is not a scientific curiosity. It is the foundation of every decision a grower makes about their land.
Microbe is an umbrella term for any living organism too small to see. In soil, four groups do the work, and each plays a distinct and irreplaceable role.
Single celled, present in almost every environment on earth. In soil they decompose organic matter, fix atmospheric nitrogen into plant available forms, produce growth promoting phytohormones, and occupy space on root surfaces that would otherwise be taken by pathogens. The genus Bacillus, which forms the core of our formulation, survives extreme conditions by forming endospores. Dormant structures that lie inactive for years until conditions favour germination. When they wake, they work.
Where bacteria work at the scale of individual root cells, fungi extend through a web of fine filaments called hyphae that can span whole root systems and connect several plants in one network. Mycorrhizal fungi form a symbiotic relationship with over 80 percent of land plant species, extending the effective root zone by up to 700 times its physical length and trading minerals for plant sugars. Decomposer fungi break down lignin and cellulose that nothing else will touch.
They grow in thread like filaments as fungi do but are classified as bacteria. They produce geosmin, the compound responsible for the earthy smell of freshly turned healthy soil. More practically they produce a remarkable range of antibiotics and antifungals. Most antibiotic drugs developed in the twentieth century came from actinomycete compounds, and in soil they serve the same purpose, holding pathogen populations down.
Single celled organisms that eat bacteria, regulating bacterial density and in doing so stimulating bacterial activity. When they consume bacteria they release part of the nutrient held inside those cells back into soil water as ammonium, nitrogen immediately available to roots. This microbial loop is one of the main routes by which nitrogen cycles through healthy soil with no synthetic input at all.
It is one thing to know microbes exist in soil. It is another to see the scale of what they accomplish. These six functions are why microbial health is the single most important indicator of agricultural soil quality.
Healthy soil is not a medium for delivering chemicals to plants. It is a living system that feeds them, defends them, and regulates water and nutrients with a precision no fertiliser programme can replicate.
Certain bacteria, including Azospirillum, Rhizobium and Bacillus species, capture atmospheric nitrogen and convert it into ammonium, the form plants absorb. Biological nitrogen fixation is free, self sustaining and infinitely renewable. In healthy soil it can supply a significant portion of a crop's nitrogen with no synthetic input.
Phosphorus is abundant in most soils but locked into insoluble mineral compounds plants cannot reach. Phosphate solubilising bacteria produce organic acids that break those bonds and release plant available phosphate. Without this process, applied phosphorus fertiliser accumulates in the soil without delivering its intended benefit.
Bacteria and fungi break down crop residues, amendments and dead roots, releasing the nutrients they hold and converting them into stable humus. Humus is the dark spongy material that gives healthy soil its structure, its water holding capacity and its long term fertility. It is built by microbes and by nothing else.
A dense, diverse microbial community is the soil's primary defence against plant pathogens. Beneficial microbes compete for space on root surfaces, produce antifungal and antibacterial compounds, and stimulate the plant's own immune response. Soil depleted of its microbial community is soil that is defenceless against disease.
Bacteria produce sticky polysaccharides that bind soil particles into aggregates. Those aggregates give soil its crumb structure, the open porous architecture that lets water infiltrate rather than run off, air reach root depth, and roots explore freely. Compaction, in many cases, is a symptom of microbial depletion.
Many soil bacteria produce phytohormones including indole-3-acetic acid, which drives root growth and branching, and cytokinins, which promote cell division above ground. Plants inoculated with these bacteria show measurably greater root mass, earlier germination, and improved tolerance of drought and salinity.
The current formulation is a liquid consortium of five strains drawn from three species, and every one was chosen for a specific, documented function in the agricultural root zone. All of them are Bacillus, and that is deliberate. Bacillus bacteria form endospores, dormant structures that survive heat, drought, ultraviolet light and long storage, then germinate when soil conditions turn favourable. A product built on Bacillus does not die in the warehouse or on the shelf. It arrives alive.
The formulation's phosphorus specialist. A root associated bacterium that colonises the rhizosphere and produces gluconic and oxalic acids capable of breaking the mineral bonds that lock phosphorus into unavailable forms. Phosphorus is abundant in most agricultural soils but bound to iron, aluminium and calcium compounds roots cannot absorb. B. megaterium releases it continuously, without additional fertiliser. In the 2025 corn trial at Prosper it was confirmed by 16S rRNA sequencing at 2.6 percent relative abundance in the treated plots, which is direct evidence of active colonisation rather than a product that simply washed through. It also produces extracellular polysaccharides that build soil aggregates over time.
Included for two capabilities. First, exceptional production of extracellular cellulase enzymes, which break down complex organic residues including lignin rich crop debris and thatch. That matters particularly in soils receiving modern short stalk cereal straw, which resists decomposition by standard microbial blends. Second, antifungal activity: certain strains produce iturin class lipopeptides that inhibit Fusarium and Pythium at the root surface. Critically it performs under anoxic and anaerobic conditions where many competitors cannot, so it keeps working in compacted or waterlogged zones.
The most extensively studied plant growth promoting rhizobacterium in the scientific literature. Selected primarily for biosurfactant production, cyclic lipopeptides including iturin, surfactin and fengycin, which change how water interacts with soil particles and root surfaces, improving infiltration and reducing the hydrophobicity that develops in degraded soil. It also produces subtilisin class enzymes that suppress a broad range of opportunistic pathogens, and competes aggressively for root surface colonisation sites. Its presence stabilises the wider community, creating the conditions in which the other members establish.
Each strain addresses a different limitation in depleted soil. B. licheniformis handles organic residue and fungal suppression. B. megaterium unlocks phosphorus at the root. B. subtilis manages water dynamics and rhizosphere stability. No single organism does all three.
More importantly they are complementary. The compounds released by B. licheniformis become substrate for the wider community, while the structural improvements driven by the other two create the environment in which all three establish more readily. The consortium is designed so that each strain makes the others more effective.
The current consortium is the foundation. Once its performance is validated across crop types, soils and geographies, the formulation expands. Each candidate species is validated individually before it enters the consortium. That is not a conservative posture. It is the only method that produces data worth trusting, because when a new organism joins a working system its contribution has to be attributable rather than assumed.
Trametes versicolor and related species degrade recalcitrant organic compounds including lignin, pesticide residues and hydrocarbons, through oxidative enzyme systems Bacillus cannot replicate. Their hyphal networks also physically improve soil structure. Already proven in our bioremediation work, and the next intended addition on the agricultural side.
The mycorrhizal extension of plant root systems is one of the best documented phenomena in soil biology. Colonisation extends the plant's effective nutrient foraging zone by up to 700 times, improving water and mineral uptake under drought and low input conditions. A natural next layer once the bacterial foundation is stable.
P. protegens, P. fluorescens and P. chlororaphis are documented degraders of recalcitrant pesticides and herbicides in contaminated soil. Their inclusion would extend the consortium's bioremediation capability into fields with long histories of chemical input that have damaged the native microbiome.
A. brasilense and related species are among the most studied free living nitrogen fixing bacteria in the agricultural literature. Their addition would deliver a genuine biological nitrogen source alongside the phosphorus work already done by B. megaterium, reducing synthetic nitrogen dependency across the cropping system.
Soil that supports a diverse and active microbial community requires less synthetic fertiliser to reach the same or better yield. It holds more water, reducing irrigation demand. It resists pathogen pressure without chemical intervention. And it builds organic matter year on year, improving its own fertility rather than declining.
In trials with industrial hemp, vegetables and row crops, growers who brought microbial inoculants into their programme reported reduced input costs, improved crop uniformity, and measurable gains in soil organic carbon within two growing seasons.
Microbes are not a technology laid over existing agricultural practice. They are the mechanism through which soil was always intended to function. What we offer is the restoration of what was there before it was taken away.
We supply the product and pay for the sequencing. You provide the ground, apply it to the protocol, and send us samples at the end of the season. Free for 2026 and 2027.
